Tuya door sensor - external sensor

Hardware
1

Hi everyone

I bought a tuya door sensor wifi. My goal is to modify it and connect two wires to it, to simulate the opening/closing of the sensor. Where should I connect them? I thought I’d find a magnetic contact but I don’t see it. I attach photos

The magnetic reed switch is probably on the other side of the PCB.

I soldered the circuit to get the magnetic switching sensor out. I attached the extension sensor to the keyhole to determine the lock status of the door.
I tried it for 1 week. There’s a problem: the sensor runs out of battery unusually quickly.
Has anyone tried it yet?
